What is the tune? i.e. static and total ignition timing and when. Do you have a wideband O2 you can tune the carb with?

Just set my initial to 20 degrees at the weekend. Was showing 35 max. Vacuum at idle was actually just into over run on my vac gauge. Not got a sensor to tune no, would I need a boss in the header for one?
